Over the past couple weeks, I've been working on getting the ral(4)
driver updated for the 35xx chipset. Specifically version 0x3060 from
an Edimax EW-7128Gn. Although the mailing list page says tech@ is not a
"tech support", I was privately directed from misc@ to post in tech@.
I've previously tried getting a hold of mediatek (Linux vendor code
providers) and [email protected] (from ral(4) manpage, mailer daemon -
failure to deliver).
I've been having trouble comparing the vendor provided code against the
ral(4) driver. The hard part, is that I don't know the "correct"
information for certain registers (because I have nothing to compare the
3060 eeprom against). Is there anyone else I can contact about this? or
anyone running ral(4) (2860 or 3090) who would like to enable the debugging?
I've made the needed changes to /usr/src/sys/dev/pci/pcidevs, and
enabled the debugging macro of ral(4)'s "sys/dev/ic/rt2860.c" driver.
Here is the associated output of dmesg:

At first I thought the 3060 used eeprom, but I'm now certain it uses
efuse. Because this information is correct:
MAC Address (80:1F:02 = Edimax Brand)
MAC/BBP RT3572 (comment in vendor code states: 35xx chips all report
3572 from eeprom)
MIMO 1T1R, (3060 has 1tx ring, and 1rx ring)
(TSSI 5GHz seems to be correct, the 3060 doesn't have 5GHz support AFAIK)
Everything else I cannot prove to be correct. Furthermore, I'm fairly
certain EEPROM region code=0x0001 is incorrect. Wikipedia's list of
WLAN channels for the USA matches the vendor code definition of region
9. Eeprom (from 2860 code) reports region 12, which includes 3 channels
not used in the USA.
I've profiled all the vendor code between 2860 and 35xx. Now I'm going
to profile between 35xx and 3090. In the meantime, I was hoping to get
in contact with someone who knew more about the ral(4) driver, or
wireless drivers in particular.
Thanks!
